VENTILATGR FOP MGTGR VE Application filed 15, l

dal object oi the invention conl l in the provision ot an improved simpliticd 'torni oli ventilator consisting ot a plu rarity et' associated fined? non-movable parts and wherein said parts rie grouped so as to oil'ectively exclude the Weather hut to permit oit tree and unrestricted circulation ot the ritiated through and from the ventilator.

The invention consists in the provision of a ventilator ot the character aforesaid comprising; an arcuate casing applied to the root ot a niotor vehicle, or other enclosure, and wherein the curved top ot the casina` is formed 'ivith a plurality ot iiXed air inlet and outlet openings., beneath which is araneed an arch or haiti-le Wall which is interposed between the flue of the ventilator and the inlet and outlet openings in the arcuate top oi' the c; ingr, the arrangement being;` such that the movement oil` the vehicle will set up air circulation within the ventilator producing' induced drafts hy means oit which the vitiatet air et the enclosure is positively drawn through the outlet flue ot the ventilator and diflfcharged to the atmosphere.

lilith these and other objects which will appear as the description proceeds, the invention consists in the novel features of construction, coinliiinations et' elements and arrangements or" parts hereinafter to be fully described and pointed out in the appended claims. f

ln the aecoi'npanying drawing:

llia'ure 1 is a perspective vieuT of the improved ventilator comprising the present invention, .i

Figure 2 is a vertical longitudinal section-- al view taken therethrouhnl and Figure 3 is a transverse sectional view on the line 3--3 or' Figure 2.

Referring' more particularly to the drawings the numeral 1 designates the roof et a motor vehicle which is formed to include a ventilator opening` 2, adapted to be applied to the upper surface of the root, and adjacent to said opening.' is the ventilator 3 comprising the present invention. 2

.ln its preferred form my improved ventilator consists of a 'sheet metal structure T ie princi rie 1 i y upon the upper surface of the roof au s ln this instance the plate fl is o t substantially rectangular contig ration and, adjacent to the center thereof is provic ed with an upstanding` collar G4, arranged in axial registration with the opening` 2, and in which is positioned the upper end oli an outlet ilue T, which establishes communication hetiveen the interior o't the motor vehicle and the ventilator The tine l may be provided with an adjustable damper or valve structure 8 'for regulatineY air flow therethrough.

ln the present forni ol.2 the invention the ventilator includes an arcuate top Stof substantially arched or convex coni'iguration. .lhis top is provided adjacent to the center thereof with a plurality oi circular outlet openings 10, and adjacent to the openings 10, the top 9 is `termed to include slots 11. which are protected by hoods 12, .integral With the top .9,so that the hoods will he open alone` one side thereof only, as shoivn in Figure Beneath the top 9 and located Within the ventilator there is mounted a baille Wall 13. rlhis Wall is also of arched construction to correspond with the ,urvature `vof the top 9, and the ends of the Wall 113 are secured by inea s oi' bracket pieces 11i to the vert-ical sides 15 ot the top 9. Centrally of its length the Wall 185 immediately beneath the openings 1 0, is provided with a substantially J shaped rib 16 Which extends transversely beneath the under side ot the top 9. By reference to Figure 3 it will be observed that the Width ot the Wall 13 is materially less than that of the top 9, so that air circulation spaces 17 Will be provided around the side edle'es of the wall 13 and the inner surfaces of the sides 15. The sides 15 in this instance have their eXtreme lower edges slightly spaced as at 18 `from the upper adjacent surfaces ot the plate 4e so as to produce outlet openings hy means or" which Water or moisture is discharged from within the ventilator.

ln operation, it Will he observed that Lvl-ien the vehicle, upon which the ventilator is mounted is moving7 in a certain direction air ivill be forced through the hoods 12 on the lelt side ot is re rl`his in passing; through the ventilator strikes thelivall 13., and is deflected by the rib 16 outwardly through the openings 1 0. This circulation et air results in creating; aldraft Within the ventilator hy .means et which. the vitia lll) vtrom reaching the iiue.

E LSG air is drawn u nvardly kthrough the iliie 7.

around the edges of the vfall 1B by ot the spaces 1.7 and then forced through the openings 10. Also, the hoods 12 on the right hand side oi' Figure 2 are used to dispel the vitiated air. Thus, due to the direction oi ii'iovement ot' the vehicle a suction eii'ect is produced in the slots 11 provided in the hoods 12 shown on the right side et yFigure 2. This suction is utilized to dran' the air through the flue and to release the saine through said last named hoods. Due to the construct-ion ot' the ventilator the saine is readily operative regardless et the direction oitl movement oi the vehicle. rihe baille wall 13 is arranged immediately beneath the openings inthe top 9, and over the open upper end ot the tine 7. Vilus the Wall 1.3 serves to prevent water or mois ture entering the ventilator trein reachingI the tiue and then the interior of the vehicle. The collar G provided' at the ripper end of the flue also acts as a trap to prevent Water or moisture in the bottoni of the ventilator Due to the openings 18 Water accumulation vfitliin the ventilator is readily and freelyv discharged. lt vill be observed that the preent invention provides a ventilator ot simple construction, eliminating movable and adjustable parts, is loiv in height so as not to interfere Wit-li vehicle operation or overhead clearance and is oi" such design as to avoid marring or interfering with the general ont lines of the vehicle to vrliicli itis applied.

Vhat is claimed is:
